 The air-dried salt lost slightly in weight at 100°, This loss corre- 

 sponded to about one half-molecule of crystal water; it is possible, 

 however, that it was hygroscopic moisture alone.

Diargentic Anilmitcoxyclilorate, Ag.,Cj,jHgClNO,. — When argentic 

 nitrate is added to a cold aqueous solution of anilmucoxychloric acid, 

 a pale yellow gelatinous precipitate is formed, which is hard to wash 

 and prepare for analysis, and doubtless contains one atom of silver. 

 If, however, the acid is dissolved in two equivalents of dilute ammonic 

 hydrate, and this solution poured into an excess of argentic nitrate, a 

 bright orange-yellow flocculent precipitate is thrown down, which be- 

 comes more compact on standing, and contains two atoms of silver. 

 This salt showed but slight discoloration when warmed for some time 

 with an excess of argentic nitrate in a feebly ammoniacal solution.

Dipotassic Anibmicoxy chlorate, K^.CiqH^CIXO.j. — When an alcoholic 

 solution of potassic hydrate was added, in slight excess, to a solution 

 of anilmucoxychloric acid in dry ether, a pale yellow salt was precipi- 

 tated, which when dried in vacuo over sulphuric acid and powdered 

 sodic hydrate proved to contain two atoms of potassium.
